Processing technology for quick-frozen soft-shelled turtle

Abstract

The invention discloses a processing technology for a quick-frozen soft-shelled turtle, which comprises the following steps of: 1) using living soft-shelled turtles as raw materials; 2) cutting the necks of the soft-shelled turtles to slaughter the soft-shelled turtles to drain blood; 3) manually removing outer surface membranes; 4) crossly opening the bellies of the soft-shelled turtles or circularly opening the backs of the soft-shelled turtles; 5) clearing all internal organs and grease; 6) shearing off all nails of the soft-shelled turtles; 7) washing the soft-shelled turtles with tap water; 8) checking one by one; 9) degreasing and removing smell by using composite salt solution; 10) draining water and rinsing for 30min, 11) draining water after rinsing, and treating the meat of the soft-shelled turtles by using food antifreeze agent, water-retaining agent and antioxidant; 12) vacuum packaging; 13) enabling central temperature to rapidly reach a value below 18 DEG C below zero for quick freezing; and 14) conducting freezing storage under an environment below 18 DEG C below zero to obtain finished products. The processing technology for the quick-frozen soft-shelled turtle has the advantages that not only can the problem that the brought soft-shelled turtles are difficult to slaughter be solved, but also the soft-shelled turtles can be sold in the market all year round and the soft-shelled turtles are convenient to preserve.

Description

technical field [0001] The invention relates to a quick-frozen soft-shelled turtle processing technology. Background technique [0002] Chinese soft-shelled turtle ( Trionyx sinensis ), commonly known as soft-shelled turtle, belongs to the order Testudinata, the family Trionchidae, and the genus Turtle ( Trionyx ).
